Part Number: SN74LV244AT

Hi team,

Could you support selecting logic to meet following customer requirement?

<Customer requirement>

Q. Does TI have SN74LV244ATPW with non-inverting enable pin instead of /OE pin?

Best regards,

Takeshi Sasaki

    Active-low OE pins are a common convention for most logic devices.

    The only buffers with active-high OE are '126 devices, which come only in four channels. And none has the same electrical characteristics: SN74LV126A does not have TTL-compatible inputs; SN74AHCT126 has lower drive strength; SN74ABT126 has much higher power usage.
